Visceral Fat in Midlife: A Predictor of Alzheimer's Risk

A study presented at the RSNA meeting links visceral fat to increased amyloid and tau proteins in the brain, markers of Alzheimer's disease, decades before symptoms appear. Researchers found visceral fat accounts for 77% of the relationship between high BMI and amyloid accumulation, suggesting that managing visceral fat through lifestyle changes or medication could reduce Alzheimer's risk. The study emphasizes the importance of midlife interventions, as metabolic factors like insulin resistance and cholesterol levels can exacerbate obesity-related brain damage.
